JOHN HENRY KNIGHT, OF BARFIELD, NEAR FARNHAM, ENGLAND.

MACHINE FOR LAYING BRICKS FOR BUILDING PURPOSES.

SPECIFICATION forming part Of Letters Patent N0. 704,648, dated. July15, 1902.

Application filed December 27, 1901. Serial No. 87, l88. (No model.)

To [LZZ whom it may concern.-

Be it known that 1, JOHN HENRY KNIGHT, a subject of the King of GreatBritain, residing at Barfield, near Farnham, in the county 5 of Surrey,England, have invented a new and useful Improvement in Machines forLaying Bricks for Building Purposes, (for which I have applied forLetters Patent in Great Britain, numbered 23,084: and bearing date the18th day of December, 1900,) of which the following is a full andcomplete specification.

This invention relates to an improvement in the apparatus for layingbricks for build ing purposes for which Letters Patent No.

669,220, bearing date the 5th day of March,

20 width of the same regulated.

In the accompanying drawings, which illustrate this invention, Figures 1and 2 are views in side elevation and plan, respectively; and Fig. 3 isa view in plan showing a modification.

Throughout the views similar parts are marked with like letters ofreference.

In place of the feeding-rollers or revolving arms specified in my priorpatent aforesaid I employ a presser M, carried by a lever N,

fixed on a rocking shaft P, mounted in suitable bearings formed on orcarried by an extension of the traversing frame 0, which is constructedand adapted to operate as speci- 3'5 fled in my patent aforesaid. Motionis imparted to the rocking shaft by a hand-lever Q. The operative faceof the presser M is shaped according to the disposition of the bricks inthe wall.

and 2, the face of the presser M is flat; but if the wall is to be builtwith the English bond the face of the presser is. shaped as shown inFig.3. WhenthetraversingframeOispushed forward, the presser-M, by reasonof its inclined under side, slides up onto and over the brick or bricksbeing fed to it. The handlever N is then pressed forward in thedirection of the arrow aforesaid, which causes the If the wall is to bebuilt 40 with the Flemish bond, as shown in Figs. 1

presser M to force the brick or bricks home against the last-laid brickor bricks.

I sometimes provide the presser with a tailpiece or, which as thepresser moves forward res ts on the top of the last-laid brick orbricks, and thus prevents the presser from dropping down onto the mortarlaid on the last course.

The beam B, rack 19, plate B, axle D, crankhandle E, and cog-wheel Fpresent novel fea tures and may be of the construction specified in myprior patent.

To insure the bricks being laid in line on the face of the wall, I mayeither employ a guide-board or straight-edge, as described in my priorpatent, No. 669,220, or I may employ guide-rollers, such as H as shownin Fig. 2; but in either case I employ on the other side of the wall oneor more rollers R, mounted on or carried by a spring-controlled armpivotcd to the frame 0 and adapted to press the brick up against theguide board or roller on the face side of the wall, as shown by Figs. 1and 2.

What I claim, and desire to secure by Letters Patent, is

1. In a machine for laying bricks comprising an adjustable guidearranged parallel with and in close proximity to the position of thewall to be built, a frame mounted on the said guide, and means to causeit to positively traverse the same including an axle carried by theframe and rotated by a handle, a brick-feeding device consisting of apresser pivoted to a lever carried by a rocking shaft mounted inbearings formed on or carried by an extension of the said travels ingframe and a hand-lever for operating the same, the arrangement beingsuch that the presser on the forward travel of the machine slides overand engages the brick or bricks fed to the machine and pressesthemagainst the last-laid brick, or bricks, as setof orth.

2. A machine for laying bricks consisting of an adjustable guide Barranged parallel with and in close proximity to the position of thewall to be built, of a frame 0 mounted on the said guide, of means tocause it to positively traverse the same including an axle D carried bythe frame 0 and rotated by a han dle E, of a brick-feeding deviceconsisting of a presser M pivoted to a lever carried by a rocking shaft1? mounted in bearings formed on or carried by an extension of the saidtraversing frame 0 and a hand-1ever Q for operating the same, thearrangement being such that the presser on the forward travel of themachine slides over and engages the brick or bricks fed to the machineand presses them against the last-laid brick or bricks, and of 10 sideguides H to keep the bricks square and level, as set forth.
